2. Designed purpose of use
This AVANT Weed brush is an attachment that is suitable for use with AVANT multi purpose loaders that are
shown in Table 1. The Weed brush is an efficient tool for removal of weeds on all kinds of paved areas. The
manually adjustable, telescoping arm of the rotating brush makes it easy to remove unwanted weed from
pathways and around cornerstones, and allows working near buildings. The weed brush is equipped with a
support wheel as standard, which can be lifted and locked up to transport position if needed.
The weed brush is equipped with a steel brush which can be extended manually and turned in three different
positions: to the front, to the right side, or to the left side. The brush arm should be set to front position for
storage of the attachment. The weed brush is intended only for maintenance of level ground surfaces. Other
tools than the brush must not be installed on the attachment. The Weed brush is not designed for any other
use than what is specified in this manual and must not be used for any other purposes than what is intended
for.
The attachment has been designed to require as little maintenance as possible. The operator can perform
regular maintenance tasks. All repair work can’t be performed by the operator, and demanding repair and
maintenance operations are to be left for professional maintenance. All maintenance work must be done using
proper safety equipment. Spare parts must be identical with original specifications, which can be ensured by
using only original spare parts. A separate spare parts catalogue may be available, consult your Avant dealer.
Familiarise yourself with the manual's instructions regarding service and maintenance. Please contact your
AVANT retailer if you have additional questions about the operation or maintenance of the equipment, or if
you require spare parts or maintenance services.

5. Attaching the attachment
Attaching the attachment to the loader is quick and easy, but it must be done carefully. The attachment is
mounted to the loader boom by using the quick attach plate on the loader boom and the counterpart on the
attachment.
If the attachment is not locked to the loader, it may detach from the loader and cause a hazardous situation.
The loader must not be driven and the boom must never be lifted when the attachment has not been locked.
To prevent hazardous situations, always follow the coupling procedure shown below. Also remember the
safety instructions shown in this manual. The attachment is mounted to the loader as follows:
WARNING
Crushing risk - Make sure that an unlocked attachment will not move or fall over.
Do not stay in the area between the attachment and the loader. Mou
nt the attachment
only on level surface.
Never move or lift an attachment that has not been locked.
Avant quick coupling system:
Step 1:

Lift the quick attach plate locking pins up and turn them backwards into the slot
so that they are locked in the upper position.

If your loader is equipped with a hydraulic attachment locking system, see
additional instructions about the use of the locking system from the relevant
manuals.
Ensure that the hydraulic hoses are not in the way during installation.
Step 2:
Turn the quick attach plate hydraulically to an obliquely forward position.

Drive the loader onto the attachment. If your loader is equipped with a
telescopic boom, you can utilise this.
Align the upper pins of the loader’s quick coupling plate so
that they are under
the corresponding brackets of the attachment.
Step 3:
Lift the boom slightly –
pull the boom control lever backward to raise the
attachment off the ground.
Turn the boom control lever left to turn the bottom section of the quick
attach
plate onto the attachment.
Lock the locking pins manually or lock the hydraulic locking.
Always check the locking of both locking pins.

13 (26)
WARNING
Risk of crushing - Avoid tipping over the attachment.
Excessive tilting or lifting of an
unlocked
attachment increases the risk of tipping the attachment over. Do not use the
automatic locking of the locking pins when the attachment is lifted more than one meter
from the ground. If the locking pins do not return to the normal position when tilting, do
not tilt or raise the attachment any more. Lower the attachment on the ground and
secure the locking manually.
WARNING
Risk of falling objects -
Prevent dropping of
attachment.
An attachment that has not been completely locked to the
loader may fall
on the boom or towards the operator, or
fall under the loader during driving, causing loss of
control of the loader. Never move or lift an attachment
that has not been locked. Before moving or lifting the
attachment, make sure that the locking pins are in the
lower position and come through the fasteners on the
attachment on both sides.
WARNING
Make sure the loader is compatible with the attachment.
Stability of the loader,
possible overload of the attachment, and compatibility of loader control
systems must be
ensured in addition to mechanical compatibility of the attachment. If you use the
attachment with a loader that is not fit to be used with the attachment model you have,
risks include tipping over, damage to attachment due to overload, and
risks related to
uncontrolled motion of attachment and its parts. If your loader is not listed in Table 1 on
page 6, ask your Avant dealer before using this attachment.
5.1 Connecting and disconnecting hydraulic hoses
On Avant loaders the hydraulic hoses are connected using the multi connector system. If you have an Avant
300-700 series loader with the conventional quick couplers and wish to change to the multi connector system,
contact your Avant dealer or service point for instructions or installation services.
WARNING
Risk of movement of the attachment and ejection of hydraulic oil -
Never connect
or disconnect quick couplings or other hydraulic components while the control
lever of the auxiliary hydraulics control lever is loc
ked on or if the system is
pressurized.
Connecting or disconnecting the hydraulic couplings while the system is
pressurized may lead to unintended movements of the attachment, or ejection of high-
pressure fluid, which can cause serious injuries or burns. F
ollow safe stopping procedure
before disconnecting hydraulics.

14 (26)
Keep all fittings as clean as possible; use the protective caps on both the attachment and
the loader. Dirt, ice, etc. may make using the fittings significantly more difficult. Never
lea
ve the hoses hanging on the ground; place the couplings onto the holder on the
attachment.
Connecting the multiconnector system:
1.
Align the pins of the attachment connector with corresponding
holes of the loader connector. The multiconnector will not
connect
if the attachment connector is upside down.
2.
Connect and lock the multiconnector by turning the lever towards
the loader.
The lever should move easily all the way to its locking position. If the lever does not slide smoothly, check the
alignment and position of the connector and clean the connectors. Also shut down the loader and release the
residual hydraulic pressure.
To disconnect the multiconnector system:
Before disconnecting put the attachment down on a solid and even
surface.
1. Switch off the auxiliary hydraulics of the loader.
2.
While pushing unlock button, turn the lever to disconnect the
connector.
3.
After ending operation put the multiconnector on its holder on the
attachment.
Disconnecting hydraulic hoses:
Before disconnecting the fittings, lower the attachment to safe position on solid and level surface. Turn the
control lever of the auxiliary hydraulics to its neutral position.
When uncoupling the attachment, always disconnect the hydraulic couplings before
unlocking the quick c
oupling plate, to prevent hose damage and any oil spills. Reinstall
the protective caps on the fittings to prevent impurities from entering the hydraulic
system.
Releasing residual hydraulic pressure:
In case residual pressure is left in the hydraulic system of the attachment, it is often possible to disconnect the
hydraulic couplings, but it may be difficult to connect them the next time. If the fittings will not connect, the
residual pressure must be released by turning the auxiliary hydraulics control lever of the loader, when the
engine is turned off. To make sure that there will not be residual pressure in the hydraulic system of the
attachment, shut down the loader engine and move the auxiliary hydraulics control lever of the loader back
and forth before disconnecting the couplings.

15 (26)
6. Operating the attachment
Check the attachment and the operating environment once more before starting to work, and that all obstacles
have been removed from the operating area. Quick inspection of the equipment and the operating area before
use are parts of ensuring safety and the best performance of the equipment.
WARNING
Hazard of thrown objects - Keep bystanders away. Note
that the attachment can throw stones, gravel, or other objects
found in the area at high spee
d. Always keep a safety
distance of at least 5 metres to other persons.
WARNING
Entanglement hazard -
Never leave the driver’s seat
when the broom is in operation
. Keep a safe distance
between the broom and other persons and stop the broom
and lo
wer it down completely whenever others are in
proximity with the broom. Never perform any maintenance or
adjustments if the broom can start by accident. Shut down
the loader engine, turn off auxiliary hydraulics and lower the
loader boom before going near the attachment.
DANGER
Risk of crushing or entanglement from contact with moving parts -
Never leave the
equipment unattended while the engine is running. Follow safe stopping procedure.
6.1 Checks before use
Check that the brush can rotate freely and that there is no string or other foreign material coiled
around it.
Use only when all pins are locked and secured in place.
Ensure that bystanders are at a safe distance when operating the equipment. Do not let anyone to
enter danger area of the boom or to stay directly in front of the loader. Also make sure that it is safe to
reverse with the loader. Never assume that bystanders will remain where you last saw them;
especially children are often attracted to the moving equipment.
Check the general condition of the attachment and the loader, and check for possible hydraulic oil
leaks. The attachment must not be used, if there is a fault in the hydraulic system of the loader or the
attachment. Refer to Chapter 7 for maintenance instructions.
Operate the attachment and the controls of the loader only when seated on the driver’s seat. Ensure
that the loader and the attachment are used in a safe manner and as intended. Do not allow children
to operate the equipment.

16 (26)
Never operate the loader or attachments while under the influence of alcohol, drugs, medication that
may impair judgement or cause drowsiness, or if not otherwise medically fit to operate the equipment.
Remember correct working methods and avoid leaving the driver’s seat unnecessarily.Practise the
use of the attachment and the controls of the loader in a safe area. If you are unfamiliar with the
particular loader model, it is recommended to practice its use without any attachments.
CAUTION
Risk of uncontrolled movement - Lock the brush arm befor
e starting the
attachment.
Check that the brush is properly locked on either side before use. Also
make sure that the hydraulic hoses are secured against contact with moving parts.
.
6.2 Use
Before starting the Weed brush:
Set and adjust the Weed brush
to
working position. Lock the brush arm
on either side of the loader as
indicated in the adjacent figure. Also
see the following chapters about
adjustments.

17 (26)
Operating the brush:
As standard, the weed brush will
rotate counter-
clockwise when the
auxili
ary hydraulics control lever is
moved to its locking position (or red
button of electric joystick is
depressed, if equipped).
In correct operating position only the
front corner of the brush is in contact
with the ground. See chapter
Adjustments.
Adjust the loader engine rpm so that the auxiliary hydraulics flow is within the recommended range for
the attachment.
Adjust the drive speed according to the operating conditions and the material being handled.
Always drive slowly while operating the brush.
If your loader is equipped with a telescopic boom, you can utilize it for a better view to the working
area.
Typically the support wheel should be set down to operating position for easier control of the
attachment. However, in some cases it might be easier to operate the brush with the support wheel
lifted to upper position.
The Weed brush can be operated while driving forward or reversing, depending on operating
conditions.
Avoid pressing the brush hard against the ground. If the front wheels of the loader tend to
lift off the ground, the attachment is pressed too hard against the ground. To avoid
damaging the attachment, make sure it is operated as intended.
Adjust the rotating speed according to operating surface. Too fast rotation combined with
hard pressing against the ground can cause the brush to wear down quickly.
Use the brush only while it is rotated. Using the brush to push material without rotating it
can cause damage to the brush.
6.2.1 Using boom floating
After setting the brush to correct operating position, the boom floating option of the loader can be switched on.
This helps to push the brush against the ground at constant force, making it easier to operate over long
distances. The floating must be switched on only after the brush is pressed correctly against the ground.
Boom floating is available for some loader models as an option.
6.3 Adjustments
The brush can be adjusted in many ways, as shown in the following chapters. Best way to operate the brush
depends on the surfaces the trimmer is operated, and the direction of travel.

18 (26)
6.3.1 Brush position
Recommended operating position:
In correct operating position the brush is
tilted both sideways and forward. as shown
in following figures.
This ensures that material is moved
efficiently aside, an
d not rotated around
with the brush.
Sideways tilt:
Adjust the sideways tilt so that the outer
edge of the brush is angled as shown in
lower adjacent figure.
The adjustment is made by turning the top
link from its middle part.
Forward tilt:
While o
perating, keep the brush tilted
slightly forward by operating the loader
boom.

19 (26)
6.3.2 Orientation
The brush arm can can be locked on either side, for easier use in different operating areas.
For transport, lock the arm on the middle position and lock the support wheel to its upper position.
Left side Right side
6.3.3 Side reach
The side reach can be adjusted as needed
by unlocking the same pin on the arm that is
used to lock the orientation of the arm.
Make sure to lock the pin after adjusting the
reach.

20 (26)
6.3.4 Support wheel
The support wheel can be locked
either transport or operation positon as
shown in the adjacent figure.
The correct operating position is
reached when the wheel slightly
touches the ground. For transport, the
support wheel is lifted up.
Make sure to lock the support wheel
with pin after reaching the desired
position.
6.4 Transport position
When driving with the loader, keep the weed brush in
the position shown in adjacent figure.
Make sure the trimmer arm and the support wheel are
locked with locking pins.
CAUTION
Keep the loader stable. Always transport the attachment as low and close to the ground
as possible. Keep the telescopic boom retracted during transport drive.
